Abstract
Anderson theory is modified to explain the scaling behavior of the E-J curves, the logarithmic dependence of the potential barrier as a function of the transport current, the decrease of the barrier as the temperature goes to zero, and other results of the studies of flux creep in high-T/sub c/ superconductors. Moreover, the method provides the possibility of estimating the main pinning parameters of superconductors by fitting the calculated and experimental data.
